Hello,
I have two crs212-1g-10s-1s+in connected with a pair of Mikrotik SFP modules S-35LC20D + S-53LC20D and a LC/LC 9/125 patch coord of 2 meters.

Both units have RouterOS 6.35.1 with default configuration, except for the management ip addres and the sfp ports autonegotiation (disabled): http://forum.mikrotik.com/t/ccr1036-8g-2s-sfp-problems/72604/1


The SFP modules are detected and with link ok:


But there isn’t any communication between the 2 devices. I can’t ping one unit from each other. And in Neighbours I can’t see the other unit. ![]()
